Siberian Flying Squirrel

• locomociónIt can glide more than 50 metres between trees on a membrane of skin (the patagium) stretched between its front and hind legs.
• It is the only gliding mammal in Europe, and its presence in a Finnish stand legally requires logging to be limited, which has put it at the centre of a decades-long argument between conservation and the timber industry.
• A cartilage rod at its wrist, known as the styliform, tensions the edge of the membrane in mid-glide and lets it adjust the wing surface as though it had a flap.
